Two-stage heating for always-on performance

While most furnaces are either off or on, the SL280V can actually deliver two different levels of heat based on how cold it is outside. This lets it fine-tune fuel use to carefully match your comfort, keeping your home warm and energy-smart.

Variable speed keeps you constantly comfortable

variable-speed blower maintains comfort with an adjustable flow of air, preventing temperature swings and blasts of air when your system starts.

Efficiency you can feel good about

  • An energy rating of 80% AFUE means the SL280V can significantly reduce your heating costs, compared to an older furnace.
  • A more efficient home environment helps contribute to a better global environment.
  • Feel good this winter and all year long knowing you can save energy and money without compromising on comfort.

Not a lot of sound, just a lot of perfect air

Because it’s designed with SilentComfort™ technology, the SL280V operates with very low noise levels.
